Would removing (or impairing with tin foil) the antenna make for a
poor-enough cell connectivity, or do you need other environmental
factors (interference, etc)?<br class="">
<br class="">
What is the current recommendation for configuration and enabling 3G
? From Michael's email, I see<br class="">

<tt class=""> </tt>For a Roadster, I presume I can ignore the two GPS
entries - the car supplies that info, right? Also, what are the
apn.user and apn.password fields? Is that our Hologram Dashboard
account? Any other settings?<br class="">
<br class="">
I'm kind of in a hole, regarding cellular service, so I can try
testing. I also would like to test the module hand over
connectivity from WiFi (supplied by the OBDII Dongle) to Cellular,
when the car is turned off. I disable the external 12v to the
dongle upon the turn-off event, since I don't have any way to do
that when the car goes to sleep. (Could definitely use a new Event
there... Vehicle.off is best when obd2ecu is driving a HUD, but for
other devices, vehicle.asleep would be better.).<br class="">

<pre wrap="" class="">I’m aware of this, and working on it.
Something strange going on in the lwip pppos api. Seems to not be returning from the shutdown call, so our simcom thread gets locked up. Also messes up the main freertos threads (I think those drive the event timers for lwip).
I am working on a re-factor of the simcom state diagram to simplify the way we drive this, and also an ability to force a state change by command. At the moment, too much is being done in state NetMode. My test-debug cycle is also way too long (plug in antenna, power up simcom, wait for cellular connectivity, wait for GSM lock, wait for mux, wait for CSQ, wait for PPP, then disconnect antenna, and wait again…), can only be done in areas of poor cellular connectivity, and is driving me crazy. That should speed up debugging this issue. I’m working on it…
Regards, Mark.
